Vapor Mist connects two communicating walls sensible to the real-time weather of their geo-localization. Differences of weather generate physical reactions on this window through space. These reactions become alternative and poetic ways of communication. This prototype uses the CityMedia device.

Problematic
How to evoke the presence of a close one despite distance, thanks to non-vebalized mediated interactions?

CityMedia
The CityMedia device—developed by Seconde Nature and the School of Arts of Aix-en-Provence—aims to take place in several cities. This interactive wall displays different applications. Mine, Vapor Mist, highlights the time/space window allowed by the wall (ex. between Aix-en-Provence, hot & warm and Strasbourg, cold & dry). It bridges the distances turning it into a simple glass. A complex weather differentiation system—difference of temperature, altitude, wind…—creates physical reactions on each sides of the wall—shadows, clouds, rain drops, vapor…—this consequences on the wall become stimuli for interaction between spectators. It propose to users tangible, poetic and intuitive communication spaces.

Wall behaviour
Different combinations of weather are prepared to react to the real-time weather between the two walls. The calculation generated can display rain drops to be whipped out from the window, fog to bz chased by moving the arms, ice to be taken off by scratching the wall or talking with signs (no sound), etc. Weather parameters used are temperature, altitude, humidity, sun and wind speed.
